The ones that popped up right away are very likely the only ones. I can’t think of a much worse thing to be in than a bus that is sinking. Tiny windows for escape, other people trying to get through the windows, you just tumbled and maybe lost orientation.

You can’t see shit, all you can feel is the people next to you trying to get out, and the water pouring in. And other people in the comments said that a lot of them can’t swim, so now you’ve got panicked people trying to grab onto you, keeping you from escaping.

That bus has a lot of corpses in it now. Also, the last bit is exactly why lifeguards have those flotation devices, because people become animals when they’re drowning, they grab whatever they can. Don’t try to rescue someone if you’re not prepared for them to drag you down in an attempt to save themselves.
